BOMB.

Specification of Letters Patent. Patented Nov. 11, 1919.

Application filed February 13, 1919. Serial No. 276,753.

To all whom it may concern Be it known that I, CHARLES L. ARCHER, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented certain new and useful Improvements in Bombs, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to bombs, and has for its object the production of an explosive bomb which is so constructed that the timeof exploding can be regulated or -controlled. p Another obj ect of my invention is the production of an explosive bomb that is safe or secure when being handled or transported. V

A still further object of my invention is the production of an explosive bomb that can only be fired after being delivered or cast, and then only upon coming in contact with resistance, which resistance will explode the bomb.

With these and other objects in view, my invention comprises certain combinations and arrangements of parts as will be hereinafter specifically described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a view in side elevation of a bomb constructed in accordance with the present invention, partly shown in section.

Fig. 2 is a sectional view taken on line 2-2, Fig. 1, and looking in the direction of the arrows.

Fig. 3 is a fragmentary sectional view of the bomb showing particularly the firing plug in a set position, while Fig. lis a similar view of the spark plug with the parts in an unset or firing position.

Fig. 5 is a section taken on line 5-5, Fig. 3, and looking the direction ofthe arrows. I

Fig. 6 is a fragmentary sectional view of the bomb, showing particularly the fuse holder.

Referring to the drawings by numerals, 1 designates the outer or primary shell or casing, and 2, the inner or auxiliary shell or casin These shells or casings 1 and 2 are pre erably made in sections, and are held together by suitable fastening means as screws 3 and 4:, Fig. 2.

The inner or auxiliary casing 2 is preferably made of considerable thickness, as

compared to the outer or primary casing 1, as the auxiliary casingcontains the gas or explosive material 5. Covering the outer surface of the auxiliary casing 2 is a casing or covering of preferably asbestos 6.

The auxiliary casing 2 is suspended in a the primary casing 1 by placing a plurality of cushioning casings 7 between the two casmgs 1 and 2. Each cushloning casing comprises an outer section'8 securedin any suitable manner at one end of the auxiliary casing 2 and, an inner or plunger casing 9 provided with a base platelO that is fastened, preferably by rivets 11, to theprimary casing or shell 1. In the outer section ,8, is positioned a coil spring 12. The tension of the springs 12 is such that the inner or auxiliary casings 2 have a slight movement, but, not sufficient to explode the bomb, without the bomb being either exployed by igniting a'fuse or by coming in forceful contact with an object. V

A plurality of the firing plugs are placed around the inner or auxiliary casing 2, being located between the primary and auxiliary casings as shown. Each firing plug comprises a cylinder or casing 13 which is provided with a reduced threaded extension '14 at its inner end; this extension 14: is threaded into an aperture formed in the auxiliary casing 2. Across the inner end of the cylinder 13 is placed a cap 15. A washer or plate 16 is secured within the cylinder 13, and slidably mounted upon the washer is a firing pinlZ, for exploding the cap 15. The firing pin 17 is provided with a head 18. Secured to the firing pin near its inner end is a plate 19, and positioned between the plate 19 and the washer 16 is a coil spring 20, which spring forces the firing pin inward or downward, against the spring 24, which spring 2 1 serves to readily operate the catch or hook 21 for releasing the firing pin 17 when the plunger pin is caused to operate. A readily-fusible sleeve 25 is placed around the plunger pin 22 between the outer end of the cylinder 13 and the head 23. The head 23 is slightly spaced from the inner face of the primary casing 1 (Figs. 2, 3, and 4) so that there might be a slight movement of the primary casing within the auxiliary casing Without exploding the bomb; however, if the primary casing 1 forcefully comes in contact with the foreign object, sufficiently to indent or depress, as shown by dotted lines 26 (Fig. 4:), to press the head 23 inwardly, compressing the fusible sleeve 25, then this compressing or indenting of the primary casing 1 will operate the catch or hook,

causing the same to move on its pivot and thereby release the firing pin 17,exploding the cap, and consequently exploding the entire bomb. I

My improved bomb is provided with a system of fuses for exploding the same "when it is desired, without the necessity of causing the bomb to be exploded by actually coming in forceful contact with a foreign ob ect. Tlns system of fuses comprlses a holder '27. This holder is constructed from non-heat conducting material, and has as many independent channels or passage-ways as there are fuses.

explode or prolong the time of explosion a considerable period. Each fuse is connected to a firing plug, by having its inner end wound substantially into a coil, as shown in Figs. 3 and 4:, and this coiled inner end is preferably embedded in a material such as sulfur 29, so that when the fuse is burnt to the sulfur 29, it will take fire and result in sufficient heat being generated to instantly melt the sleeve fuse 25, resulting in the releasing of the catch from contact with the head 18 of firin pin 17, allowing the pin to explode the cap 15.

It is to be understood that the fuses 28 are sufliciently separated or insulated to prevent all of them being set on fire when a single one is purposely lighted. Furthermore, it is obvious that if the operator desires hastening the explosion of the bomb, he can immediately light all of the fuses at one time.

In the foregoing description, it is to be understood that I have clearly described the preferred embodiment of my invention, and it will be obvious that certain minor changes can be made by one skilled in the art to 'which this invention relates, which changes or alterations may be found from time to time to be essential or needful without departing from the spirit or scope of my invention as expressed in the following claims.

. What I claim is:

1. In a bomb, the combination with a casing, of a firing plug secured to said casing, explosive means in said casing, said firing plug including means for exploding the explosive means in the casing, fusible means associated with said firing plug, and a fuse positioned contiguous to said fusible means, whereby when the fuse has been ignited and has burnt contiguous to the fusible means, said fusible means will fuse and permit the firing means in the firing plug to explode the explosive means in the casing.

2. In a bomb, the combination with a. casing, of explosive means in said casing, and a firing plug-secured to said casing and communicating with the interior thereof,

said firing plug including a firing pin,

fuse positioned contiguous to said fusible sleeve, whereby when the fuse has burnt the sleeve will be fused or melted and the firing pin will be released for exploding the bomb.
